11. Service Interaction (1) • GGOS • Global Geodetic Observing System • Project of the International Association of Geodesy (IAG) • New chair since IAG Scientific Assembly 2005: Markus Rothacher • Currently setting up its organizational structure • IVS represented in several working groups • IVS to determine representative on GGOS Steering Committee

12. Service Interaction (2) • INDIGO • INter-service Data Integration for Geodetic Operations • NASA funded within the Earth Science Research, Education and Applications Solutions Network (REASoN). • The successful community-based international scientific services have evolved data information systems well-suited to users’ needs. • Space geodetic systems will be integrated, upgraded and enhanced in response to user requirements, first steps towards realizing GGOS scientific objectives. • User interface and access will be streamlined and seamless with state-of-the-art web-based services (GSAC model).
